TransPAC2 Applications

The Open Science Grid (OSG) is a production-quality grid computing infrastructure for large scale science. The OSG capabilities and are driven by participants in experiments at the Large Hadron Collider, currently being built at CERN in Geneva, Switzerland. The OSG consists of over 20 virtual organizations (VO) including projects involved in High-Energy physics and Astronomy. TransPAC2 supports the OSG with High-performance networking expertise both nationally and internationally.

e-Very Long Baseline Interferometry (e-VLBI) is one of the most powerful techniques available for the high-resolution imaging of distant radio sources in the universe and for making accurate measurements of the motion of the earth in space. Multiple radiotelescopes scattered over the surface of the earth simultaneously record data from a radio source at streaming data rates as high as 1 Gbps for a 24-hour period. TransPAC2 provides High-performance network access to the VLBI facility in Kashima Japan.

The BELLE detector is the state-of-the-art detector to investigate CP violating phenomena with unprecedented precision at the KEK B meson factory. The CP (C=Charge conjugation, P=Parity) violation is a key to explain why the universe is dominated by the matter, not by the anti-matter. The BELLE collaboration consists of more than 40 institutions from Japan, Korea, China, Taiwan, India, Russia, USA, Australia, and Europe. TransPAC2 provides High-Performance network infrastructure and expertise for data transfers involving BELLE data.

Grid Datafarm architecture is designed for facilitating reliable file sharing and high-performance distributed and parallel data computing in a Grid across administrative domains by providing a global virtual file system. Gfarm is an expample of a global virtual file system implementation that supports a complete set of standard POSIX APIs, while still retaining the parallel and distributed data computing feature of Grid Datafarm architecture. Gfarmi provides a secure, robust, scalable and high-performance global virtual file system. In the Grid Datafarm architecture, local disks of compute nodes in a Computational Grid compose a Grid file system every file server provides not only storage but also computing resources.

The Osaka University Research Center for Ultra High Voltage Electron Microscopy (UHVEM) and University of California San Diego National Center for Microscopy and Imaging Research (NCMIR) successfully use international advanced research networks to couple the world's largest and most powerful (3 million volt) transmission electron microscope at UHVEM to a remote-use computer pavilion set up at NCMIR.
